Core API Components

1. Wallet Initialization

#include <openclaw/wallet.h>
#include <openclaw/key_derivation.h>

// Initialize wallet with mnemonic from environment
const char* mnemonic = std::getenv("WALLET_MNEMONIC");
openclaw::KeyDerivationMatrix kdm(mnemonic);

// Derive account at path m/44'/60'/0'/0/0 (Ethereum standard)
openclaw::Wallet wallet = kdm.derive_wallet("m/44'/60'/0'/0/0");

std::cout << "Wallet Address: " << wallet.get_address() << std::endl;

2. RPC Configuration

#include <openclaw/rpc_router.h>

// Configure multi-threaded RPC routing
openclaw::RPCConfig config;
config.add_endpoint("https://eth-mainnet.g.alchemy.com/v2/" + 
                    std::string(std::getenv("ALCHEMY_API_KEY")));
config.add_endpoint("https://rpc.ankr.com/eth");
config.set_thread_pool_size(4);
config.set_timeout_ms(5000);

openclaw::RPCRouter router(config);

3. Transaction Creation and Queuing

#include <openclaw/transaction.h>
#include <openclaw/queue.h>

// Create transaction
openclaw::Transaction tx;
tx.set_to("0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb");
tx.set_value("0.1"); // ETH amount
tx.set_gas_limit(21000);
tx.set_chain_id(1); // Ethereum mainnet

// Add to queue with gas optimization
openclaw::TransactionQueue queue(router);
queue.set_gas_strategy(openclaw::GasStrategy::FAST);
queue.add_transaction(tx, wallet);

// Process queue (non-blocking)
queue.process_async([](const openclaw::TransactionResult& result) {
    if (result.is_success()) {
        std::cout << "TX Hash: " << result.get_hash() << std::endl;
    } else {
        std::cerr << "Error: " << result.get_error() << std::endl;
    }
});

4. Gas Optimization

#include <openclaw/gas_optimizer.h>

openclaw::GasOptimizer optimizer(router);

// Get optimized gas parameters
auto gas_params = optimizer.estimate_optimal_gas(tx);

tx.set_gas_price(gas_params.gas_price);
tx.set_gas_limit(gas_params.gas_limit);
tx.set_max_priority_fee(gas_params.priority_fee); // EIP-1559

std::cout << "Estimated Gas: " << gas_params.total_cost_eth() << " ETH" << std::endl;

Common Patterns

Pattern 1: Batch Transaction Processing

#include <openclaw/batch.h>

openclaw::BatchProcessor batch(router, wallet);
batch.set_batch_size(10);
batch.set_delay_between_batches_ms(1000);

// Add multiple transactions
std::vector<std::string> recipients = {
    "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb",
    "0x1234567890123456789012345678901234567890",
    // ... more addresses
};

for (const auto& recipient : recipients) {
    openclaw::Transaction tx;
    tx.set_to(recipient);
    tx.set_value("0.01");
    batch.add(tx);
}

// Execute batch with automatic nonce management
batch.execute_sequential();

Pattern 2: Multi-Chain Operations

#include <openclaw/multichain.h>

// Configure multiple chains
openclaw::MultichainRouter mc_router;
mc_router.add_chain(1, "https://eth-mainnet.alchemyapi.io/v2/" + 
                    std::string(std::getenv("ALCHEMY_API_KEY")));
mc_router.add_chain(56, "https://bsc-dataseed.binance.org/");
mc_router.add_chain(137, "https://polygon-rpc.com/");

// Execute transaction on specific chain
auto eth_tx = mc_router.create_transaction(1); // Ethereum
eth_tx.set_to("0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb");
eth_tx.set_value("0.1");

auto bsc_tx = mc_router.create_transaction(56); // BSC
bsc_tx.set_to("0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb");
bsc_tx.set_value("0.01");

// Process on respective chains
mc_router.submit(eth_tx, wallet);
mc_router.submit(bsc_tx, wallet);

Pattern 3: Smart Contract Interaction

#include <openclaw/contract.h>

// Load contract ABI
openclaw::Contract erc20("0xdAC17F958D2ee523a2206206994597C13D831ec7"); // USDT
erc20.load_abi_from_file("usdt_abi.json");

// Prepare transfer call
auto transfer_data = erc20.encode_function_call(
    "transfer",
    {
        {"address", "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb"},
        {"uint256", "1000000"} // 1 USDT (6 decimals)
    }
);

// Create transaction with contract call
openclaw::Transaction tx;
tx.set_to(erc20.address());
tx.set_data(transfer_data);
tx.set_value("0"); // No ETH transfer

// Execute
queue.add_transaction(tx, wallet);

Pattern 4: Event Monitoring

#include <openclaw/events.h>

openclaw::EventMonitor monitor(router);

// Monitor Transfer events
monitor.subscribe(
    "0xdAC17F958D2ee523a2206206994597C13D831ec7", // Contract
    "Transfer(address,address,uint256)",
    [](const openclaw::Event& event) {
        std::cout << "Transfer detected!" << std::endl;
        std::cout << "From: " << event.get_param("from") << std::endl;
        std::cout << "To: " << event.get_param("to") << std::endl;
        std::cout << "Amount: " << event.get_param("value") << std::endl;
    }
);

// Start monitoring
monitor.start();

Configuration

# Required
export WALLET_MNEMONIC="your twelve word mnemonic phrase here"
export ALCHEMY_API_KEY="your_alchemy_api_key"

# Optional
export OPENCLAW_RPC_TIMEOUT=5000
export OPENCLAW_THREAD_POOL_SIZE=4
export OPENCLAW_GAS_STRATEGY=FAST  # Options: SLOW, MEDIUM, FAST
export OPENCLAW_LOG_LEVEL=INFO     # Options: DEBUG, INFO, WARN, ERROR

Configuration File (openclaw.conf)

[network]
chain_id = 1
rpc_endpoints = https://eth-mainnet.alchemyapi.io/v2/${ALCHEMY_API_KEY},https://rpc.ankr.com/eth
timeout_ms = 5000

[gas]

[threading]
rpc_thread_pool_size = 4
transaction_processor_threads = 2

[security]

Loading Configuration in Code

#include <openclaw/config.h>

openclaw::Config config;
config.load_from_file("openclaw.conf");
config.load_from_env(); // Override with environment variables

openclaw::RPCRouter router(config.get_rpc_config());
openclaw::GasOptimizer optimizer(config.get_gas_config());

Troubleshooting

Issue: RPC Connection Timeouts

// Increase timeout and add fallback endpoints
config.set_timeout_ms(10000);
config.add_endpoint("https://cloudflare-eth.com");
config.enable_automatic_failover(true);

Issue: Nonce Conflicts in Concurrent Transactions

#include <openclaw/nonce_manager.h>

// Use centralized nonce manager
openclaw::NonceManager nonce_mgr(router, wallet.get_address());

for (auto& tx : transactions) {
    tx.set_nonce(nonce_mgr.get_next_nonce());
    queue.add_transaction(tx, wallet);
}

Issue: Gas Price Too High

// Set maximum acceptable gas price
optimizer.set_max_gas_price_gwei(300);

try {
    auto gas_params = optimizer.estimate_optimal_gas(tx);
    tx.set_gas_price(gas_params.gas_price);
} catch (const openclaw::GasPriceTooHighException& e) {
    std::cerr << "Gas price exceeds limit: " << e.what() << std::endl;
    // Retry with lower priority or wait
}

Issue: Memory Leaks in Long-Running Applications

// Properly cleanup resources
{
    openclaw::TransactionQueue queue(router);
    // ... use queue
} // Queue destructor called, resources freed

// Or explicitly clear
queue.clear_completed_transactions();
router.close_idle_connections();

Debug Logging

#include <openclaw/logger.h>

openclaw::Logger::set_level(openclaw::LogLevel::DEBUG);
openclaw::Logger::enable_file_output("openclaw_debug.log");

// Logs will show detailed RPC calls, transaction construction, etc.

Advanced Usage

Custom Gas Strategy Implementation

#include <openclaw/gas_strategy.h>

class CustomGasStrategy : public openclaw::IGasStrategy {
public:
    openclaw::GasParams calculate(const openclaw::NetworkState& state) override {
        openclaw::GasParams params;
        // Implement custom logic
        params.gas_price = state.base_fee * 1.2;
        params.priority_fee = state.median_priority_fee * 0.8;
        return params;
    }
};

optimizer.set_custom_strategy(std::make_unique<CustomGasStrategy>());

Transaction Simulation Before Submission

#include <openclaw/simulator.h>

openclaw::Simulator sim(router);
auto result = sim.simulate_transaction(tx, wallet.get_address());

if (result.will_revert()) {
    std::cerr << "Transaction will revert: " << result.get_revert_reason() << std::endl;
} else {
    std::cout << "Estimated gas used: " << result.gas_used() << std::endl;
    queue.add_transaction(tx, wallet);
}
